Cone of Uncertainty Graphic with Events in Time

I’ve always received great feedback when describing the cone of uncertainty to groups on a whiteboard using events in time rather than simply an abstract timeline.  Today I put a graphic together that I can easily share or refer to.  Thought I’d post it for others as well.  Feel free to use it and let me know what you think. 

Disclaimer: All events are provided as examples which can and may occur as you work toward solving a problem.  I’m not advising you to include these explicitly in your process.
